Can an Android Toast be longer than Toast.LENGTH_LONG?

AndroidMobile DevelopmentApps/Applications

Sometimes we need to display more time then LENGTH_LONG. This example demonstrates how to show toast longer than Toast.LENGTH_LONG.

Step 1 - Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 - Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/parent"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity"
   android:gravity="center"
   android:background="#33FFFF00"
   android:orientation="vertical">
   <TextView
      android:id="@+id/text"
      android:textSize="18sp"
      android:textAlignment="center"
      android:text="click to show toast at top"
      android:layout_width="match_parent"
      android:layout_height="wrap_content" />
</LinearLayout>

In the above code, we have taken a text view. when a user clicks on text view, it will show toast for 1000 ms.

Step 3 - Add the following code to src/MainActivity.java

package com.example.andy.myapplication;
import android.os.Build;
import android.os.Bundle;
import android.os.Handler;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.view.Gravity;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
   int view = R.layout.activity_main;
   TextView text;
   @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(view);
      text = findViewById(R.id.text);
      text.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            final Toast toast = Toast.makeText(MainActivity.this, "Sample Toast", Toast.LENGTH_LONG);
            toast.setGravity(Gravity.TOP, 0, 250);
            toast.show();
            Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
               @Override
               public void run() {
                  toast.cancel();
               }
            }, 50000);
         }
      });
   }
}

To show toast for 1000ms we have used handler as shown below -

final Toast toast = Toast.makeText(MainActivity.this, "Sample Toast", Toast.LENGTH_LONG);
toast.setGravity(Gravity.TOP, 0, 250);
toast.show();
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
   @Override
   public void run() {
      toast.cancel();
   }
}, 1000);

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen -

In the above code, it shows the initial screen when user click on Text view, it will show toast for 1000ms as shown below -
